Configuring Related Inlines and Admin Hooks
Explore how to efficiently manage related data by embedding child records using inlines in Django admin. Learn to expose read-only fields, override lifecycle hooks like save_model and get_queryset to implement custom business logic and audit logging. This lesson helps you create a streamlined admin interface that enforces rules and presents complex relational data effectively.
We'll cover the following...
When managing complex data structures, forcing administrators to navigate back and forth between different pages to edit related records is inefficient. We can solve this by embedding child records directly into the parent change form. Furthermore, we often need to customize how forms handle read-only data and intercept background database operations to enforce custom business logic.

Since our Question model has a foreign key to Author, we can manage a list of questions directly inside the author change form.
Django provides two built-in inline classes. admin.StackedInline renders forms ...
